Celeste, could be many different things. They shouldn't regurgitate their food. It's not healthy for them and only a few reasons they would, something startled the snake. Temperature can be an issue but wouldnt be the reason for regurgitating the food if it already thought it was fine enough to eat it and started to. Most snakes if it's too cold will refuse to eat it at all.
It could be maybe it got stuck? Was it a bit too big for him/her? |
